Unterrothorn

The Oberrothorn (3,414 m) is a mountain of the Swiss Pennine Alps, overlooking Zermatt in the canton of Valais. Its summit can be easily reached via a trail on its southern flank, from the Unterrothorn cable car station or from Sunnegga. Claims are often made that the Oberrothorn has one of the highest hiking trails in the Alps, or that it's the highest Alpine summit which can be walked up. Such statements are subjective, but do reflect the mountain's unusual accessibility for an Alpine summit of its height. Due to its location to the east of Zermatt, hikers on the main route up and down the mountain are afforded excellent views of the Matterhorn, across the valley, with the popular Hornli Ridge ascent route being prominent.

The Grünsee ("Green Lake") is a small lake near Zermatt, Switzerland, which is fed by the Findel Glacier. It is quite remote and is only accessible by foot, a small hub of the many footpaths in the area. There is a small hamlet nearby of the same name.

The Bösentrift is a mountain of the Pennine Alps, overlooking Täsch and Zermatt in the canton of Valais. It lies north of the Oberrothorn.

The Moosjisee (also Mossjesee, Mosjesee, Moosjesee) is a reservoir in the Findeltal valley above Zermatt in the Swiss canton of Valais. The lake is located at an elevation of 2,139 m (7,018 ft) slightly north of the Findelbach river. The reservoir is used for power generation and snowmaking. It is fed in part by the glacial milk of the Findel Glacier and therefore gets its characteristic milky turquoise color.

The Gant-Hohtälli Aerial Tramway is a large-cab cable car near Zermatt, Switzerland. It is 2,707 metres (8,881 ft) long and spans an elevation of some 1,057 metres (3,468 ft). This cable car is notable in that it runs over the tallest aerial lift pylon in Switzerland, with a height of 94 metres (308 ft).

The Hohtälli is a mountain of the Swiss Pennine Alps, located southeast of Zermatt in the canton of Valais. It lies on the range that separates the Findel Glacier from the Gorner Glacier, between the Gornergrat and the Stockhorn. Its summit has an elevation of 3,275 metres (10,745 ft) and includes a cable car station. The Hohtälli is part of a ski area and features several ski runs leading down the mountain.

The Zermatt–Sunnegga Funicular, also known as the Standseilbahn Zermatt–Sunnegga, or short SunneggaExpress, is an underground funicular railway in the canton of Valais, Switzerland. It links a lower station in the resort village of Zermatt, with an upper station at 2293 m Sunnegga, 698 m above, and forms the first link in the route to the Sunnegga Paradise ski area. The funicular was heavily modernized by Doppelmayr in 2013.The line has the following properties: The funicular is operated by Zermatt Bergbahnen AG since 2002, after it absorded Standseilbahn Zermatt-Sunnegga AG that built it.

The Rote Nase (German for "Red Nose") is a mountain of the Swiss Pennine Alps, located east of the Gornergrat in Valais. The summit is 3,251 m (10,666 ft) above sea level. It is located to the Southeast of the town of Zermatt, and features several ungroomed ski runs leading down the mountain. The summit can be accessed using either a T-bar lift running up from lower down the mountain or a cable car running from Hohtälli.

The Kölner Observatorium für SubMillimeter Astronomie (KOSMA) was a radio telescope for submillimeter astronomy located at 3,135 m (10,285 ft) on Gornergrat near Zermatt (Switzerland). It was operated by I. Physikalisches Institut, University of Cologne, and Radioastronomisches Institut, University of Bonn.The telescope had a primary diameter of 3 m (9.8 ft), and a secondary diameter of 0.27 metres (0.89 ft). It was equipped with heterodyne receivers covering 210 to 820 GHz, corresponding to wavelengths between 0.35 and 1.4 mm, for observations of lines from the interstellar medium.Because of the good climatic conditions at the altitude of 3135 m (10285 ft), astronomical observatories have been located in both towers of the Kulmhotel at Gornergrat since 1967. In 1985, the KOSMA telescope was installed in the southern tower by the Universität zu Köln and, in the course of 1995, replaced by a new dish and mount. In the northern tower, a 1.5 m infrared telescope was operated until 2005 by an Italian association of universities (TIRGO). In 2010, the telescope was moved to a site in Yangbajain in Damxung County in Tibet at an altitude of 4300m and renamed CCOSMA.

The Gornergrat (English: Gorner Ridge; 3,135 m (10,285 ft)) is a rocky ridge of the Pennine Alps, overlooking the Gorner Glacier south-east of Zermatt in Switzerland. It can be reached from Zermatt by the Gornergrat rack railway (GGB), the highest open-air railway in Europe. Between the Gornergrat railway station (3,090 m (10,140 ft)) and the summit is the Kulm Hotel (3,120 m (10,240 ft)). In the late 1960s two astronomical observatories were installed in the two towers of the Kulmhotel Gornergrat. The project “Stellarium Gornergrat” is hosted in the Gornergrat South Observatory.

The Telescopio InfraRosso del Gornergrat (TIRGO), or the Gornergrat Infrared Telescope, was located on the northern tower of the Kulm Hotel at Gornergrat (3,135 metres (10,285 ft) altitude) near Zermatt, Switzerland. It was a 1.5-metre (4.9 ft) Cassegrain telescope with a tip-tilt correcting secondary and optimized for infrared observations, but was decommissioned in March 2005. The telescope and related instrumentation were run by the Istituto di Radioastronomia (IRA - C.N.R.), sezione di Firenze (former CAISMI), with the assistance of the Osservatorio Astrofisico di Arcetri and the Dipartimento di Astronomia e Scienza dello Spazio of the University of Florence.

The Gornergrat Kulm Hotel is a hotel and observatory located on the Gornergrat, at 3,120 metres above sea level. It can be reached from Zermatt via the Gornergrat railway, the terminus station being located 100 metres away. The hotel includes an observatory, two restaurants and a small shopping mall. A first hotel was built on the Gornergrat in 1896, two years before the completion of the Gornergrat rack railway. As the tourist traffic increased, the current larger hotel was built between 1897 and 1907. Given the clean air and good light conditions of the area, a dome was built on each of the two towers of the hotel in 1996. The KOSMA telescope was installed in the southern tower while the Gornergrat Infrared Telescope was installed in the northern tower.
